 Hello everybody! In this video, I'm going to show you how to recover lost data after you reinstalled your Linux operating system or after you've formatted the hard disk. In our channel and blog, you will find solutions to any problem, from installing an operating system or configuring it, to fixing possible bugs and errors or optimizing mobile gadgets. Our specialists will answer any questions you ask in your comments under the videos or articles. Almost every novice user knows how it feels to lose data after reinstalling the operating system. You may have forgotten to copy important information from the system disk before you start the reinstallation process, and now all of those files are gone. It's a bitter feeling of trying to find the important data and discovering it doesn't exist anymore. Fortunately, there are many solutions nowadays that can help you get your data back. One of them is Hetman Partition Recovery, a well-tried and reliable utility globally recognized for successful data recovery. As long as there is no version for Linux, I'll show you a trick how to run this utility on Linux and recover missing data from the hard disk. To make the utility work in this environment, we need a virtual machine with a Windows operating system. As I said before, there is no version of Hetman Partition Recovery for Linux, but the existing version for Windows can recover files from Linux disks as well. It supports almost every file system used in Linux. To run the utility, you need a virtual machine, for example one based on VMware. One of the most popular applications of this kind, and you shouldn't have any difficulty installing it. VMware is not distributed with open source code, but it comes in two variants – a commercial Pro version and a free version with basic functionality. The Pro version has a trial limitation of 15 days, and that should be enough to recover the lost data. I'll show you how to install a VMware virtual machine, create a machine with Windows 10 and recover your lost data from Ubuntu version 1804. To install VMware, download the installation file. You can find the latest stable version on its official website. We need a version for Linux. Select to save the file and wait until it is downloaded. In addition, you need to install components required for VMware, GNU compiler collection and buildEssential. You need to set permissions for their downloaded file. Right-click on the file and open properties, jump to the tab permissions and check the box next to Allow Executing File as Program. Go to the Downloads folder and run the Terminal from there. Do it by right-clicking on an empty area in the folder and selecting Open in Terminal. Before installing any software, you need to update the Packager repository with the following command – sudo apt update. After that, install GNU compiler collection and buildEssential that will be used for VMware. Here is the command to use. Hit Yes to confirm your action and then Enter. For further actions, you need the full name of the VMware package file. For this purpose, list the files in your Downloads folder with the following command. Copy the full name of the downloaded file. You'll need it to extract the files from the package. In the Terminal, type sudo .slash and paste the package name. This is how the command looks like. When the files are extracted, the VMware installation window should appeal. If it doesn't, go to the list of installed applications and launch it from there. When it starts, select the configuration settings and proceed with the installation. When it's over, you'll see the corresponding notification about it. When started for the first time, the program asks you to enter a license key, but we choose FreeTrial for 30 days. Now you can create a virtual machine. To create a virtual machine with a specific operating system, you have to download an image of such system first. Go to the Microsoft website and download the ISO file containing the version of Windows you need. After the image is downloaded, start VMware as a superuser or root. For this purpose, exit the program and enter the following command in the Terminal. sudo VMware This will help you to avoid possible issues when connecting a physical disk at a later time. In the Programs window that opens, click File -> New Virtual Machine. Select Typical Configuration type. Next, check the box for Installer Disk Image File ISO and specify the path to the downloaded image of the operating system. Next, set the name of the virtual machine and change its location if necessary. If you are going to recover data from the system disk, it's better to choose a different disk for installation, because otherwise this process may override the data you are trying to restore. Here, you can set the virtual machine disk size, check the box next to Store Virtual Disk as a single file, and click Next. In the Next window, you can access virtual machine settings, and in the first line choose the amount of system memory to be allocated for this machine. Of course, the more is the better, but you have to consider how much RAM is installed on your PC. If you assign most of it to the need of the virtual machine, your real computer may freeze, so think twice. Other settings are not as important at the moment, so close them and click to finish. Now the virtual machine is ready. The last step is to launch it and install the operating system. The installation begins as soon as you launch the machine. In this case, it follows the same procedure as if it were an ordinary computer. Just follow the directions and wait until all elements are installed. Visit our channel for a detailed video tutorial about installing Windows, and you can find the link in the description below. Now, use the virtual machine settings to add the physical disk from where you want to recover data. To make sure your machine will boot from the hard disk and will not start the installation every time you launch it, uncheck the Connected option in the CD-DVD tab. Right-click on the virtual machine to open its settings. Select CD-DVD and uncheck this option. Below, find the Add button, click on it and select a hard disk. Specify its type and in the next window check the box for Use a physical disk. Next. Select the necessary device from the list. If you find it difficult, open the disk utility and find the disk you need by its name or size. Select the disk and click Next. Then hit Finish to complete this step. Now, start the virtual machine and wait until the operating system boots. To connect a USB drive, plug it into your computer's port and in the VMware app below, enable it by clicking on the device and selecting Connect to host. After that, it should be displayed in the program too. To get things going, download and install the program. Open your browser, download and run Hetman Partition Recovery. If you did everything right, you will see your disk in the Drive Manager. Right-click on it, open. For status, try Fast Scan. The utility will analyze the disk and display the detected information in the right-side panel. This scan type requires very little time. But if the Fast Scan can't find the information, then go for full analysis. When the analysis is over, open the folder where the lost information used to exist, select the files you want to restore and click Recovery. Specify the path for saving the lost data and click Recovery again. When the process is over, you will find the recovered files in the folder you have chosen for saving them. Also, our program can create a disk image and then conduct all recovery operations with this image, which increases your chances to restore the deleted information successfully, because multiple rounds of scanning may result in data overwriting. Hetman Partition Recovery will help you restore files lost after removing or formatting partitions after system errors, virus attacks and other scenarios that involve loss of valuable data. It can also recover data from internal and external hard disks, USB storage devices, SD memory cards, digital cameras and other devices used to store information.
